[Insight-users] Methods of RelabelComponentImageFilter

[Gaëtan Lehmann]

Hi Gopal,

For that problem also, you should look at the contribution I have  
posted last week on the insight journal.

   http://insight-journal.org/InsightJournalManager/view_reviews.php? 
back=index.php&pubid=176

It provides some classes for this kind of filtering.
For your particular problem, itk::LabelShapeOpeningImageFilter will  
do exactely what you need.
